Ofer Biton admitted to filing a false document when applying for an investor visa in 2010, the Daily News reported.

The no-jail deal promised Biton three years of supervised release, though a judge can still impose a sentence of up to six months behind bars, the paper said.

"From Day 1, the congressman has said that he has had nothing to do with him," Grimm spokeswoman Carol Danko told the Advance. "He only knows what he has read in the news today."

Biton, an Israeli citizen, helped Grimm raise between $250,000 and $300,000 from the Manhattan congregation of Upper East Side Rabbi Yoshiyahu Yosef Pinto.

That money is at the center of allegations that Grimm (R-Staten Island/Brooklyn) accepted illegal campaign donations that year. The case is being investigated by the FBI.

Grimm, a former FBI agent and Marine veteran of the Gulf War, has denied any wrongdoing.

Biton likely faces deportation proceedings. The plea deal does not mention cooperation as a condition, the News said, but the government and the judge agreed to release Biton from house arrest.

Biton was accused of not telling the truth about where he got $500,000 that he loaned to a company as part of a government program under which the transaction would have made him eligible for a permanent visa.

Grimm had previously told the Advance that Biton went with him when he met with members of the rabbi's congregation to solicit donations for the 2010 race, and that Biton would keep a list of people whom Grimm met.

Separately, Biton and publicist Ronn Torossian are being investigated for possibly embezzling millions of dollars from Rabbi Pinto.
